History of electric cars than we are now the most common internal combustion engine driven vehicles to early. Father of Hungarian inventor DC motor engineer A Niushi · abyad Lick ányos Jedlik as early as 1828 in a laboratory test of the mobile device electromagnetic rotation. American Thomas Davenport Thomas Davenport produced the first car driven by a DC motor electric vehicle in 1834. 1837, Thomas thus obtained the first patent US motor industry. Between 1832 to 1838, Scotsman Robert Anderson Robert Anderson invented the electric drive of the carriage, which is a primary battery can not be charged using a vehicle driven. 1838 Scotsman Robert Davidson Robert Davidson invented the electric drive train. Still on the road today, traveling tram is patent in 1840 appeared in the UK. 9) How to correctly use the electric car dashboard electric vehicles in China has been basically popularized range of electric vehicles on the basis of the instrument as a member, how much you know how to properly use? 5, sensors and electromagnetic properties of an electric instrument differently. The variable resistive sensor electric heating fuel gauge, and its resistance increases with decreasing oil tank plane electric cars, and the resistance value changes in the electromagnetic fuel gauge variable resistive sensor is the opposite; electric heating oil pressure gauge variable resistance value of the sensor decreases with increasing hydraulic what brand of electric cars is good, and change the value of the variable resistor electromagnetic oil pressure gauge is also just the opposite; electric heating water temperature sensor thermistor electric car modification, the water temperature at 50 ℃ resistance value of 220 Euro, 115 ℃ when the water temperature is reduced to 20 euro, while the electromagnetic water temperature thermistor sensor, the water temperature is l00 ℃ when the resistance value is still high, the temperature continues to rise its resistance value was significantly reduced. Therefore, electric and electromagnetic electric vehicles supporting the use of the instrument and its sensor should not be used interchangeably or replaced separately.
